Strong and electroweak NLO corrections to Higgs-boson production in vector-boson fusion at the LHC

We present results on the strong and electroweak NLO corrections to the production of a Higgs boson plus two hard jets via weak interactions at the LHC. The calculation includes all weak-boson fusion and quark– antiquark annihilation diagrams as well as all related interferences. We discuss corrections of different origin (QCD corrections of vector-boson-fusion type and interferences, electroweak corrections induced by quark or photonic initial states, heavy-Higgs-boson effects, etc.) and give some new results for distributions for a Higgsboson mass of 200GeV. The electroweak corrections are of the same size as the QCD corrections, viz. typically at the level of 5−10% for a Higgs-boson mass up to ∼ 700GeV. In general, they do not simply rescale differential distributions, but induce distortions at the level of 10%. The discussed corrections have been implemented in a flexible Monte Carlo event generator.
